Minisforum just launched their first Arm workstation, the MS-R1.
12-core CPU, Arm Mali G720 iGPU, 64 GB of RAM, NVMe, U.2, and PCIe expansion, and a lot more. It's a whole Arm Homelab in a box!

Just tried out the new built-in WebUI feature of llama.cpp and it couldn't be easier. Just start llama-server with a host and port, and voila!

When you ground a hot dog to an AM radio tower, it generates plasma.
Can I turn that plasma into audible sound—without a microphone?
Excited to finally post this Geerling Engineering video after working with @gavinfree.bsky.social to get the high speed footage! www.youtube.com/watch?v=nMF3...

At least the crypto bubble only massively impacted GPU pricing and availability (and HDD storage for a brief moment when all those Chia farms set up). AI is now impacting RAM and flash storage too :/

So uh, Google Cloud, could you give me a week or so before you follow in @awscloud.bsky.social and Azure's footsteps and implode from DNS issues? I need to restock on www.redshirtjeff.com

And it's a bit weird, as a hybrid SBC + microcontroller.

haha the face! It was very loud in the studio.
Fun to be able to celebrate it live. More fun to be able to hang out with chat live for a bit; usually comments are a bit less real-timey!

Is today the day? Might hit 1 million subscribers, thanks to all those who watch my YouTube channel!
One thing's for sure, my 'It was DNS' shirt is selling well with all the outages... Hang out with me on what might be my last 2025 livestream!

A tease of something amazingly exciting... Mac OS 8 for CHRP PowerPC systems! 😳
I'm working to get this CD archived properly... (along with it's friends) 💿
Super thankful to the amazing people who helped make this happen. ❤️

It's good to see DuckDuckGo getting some traction for my site referrals, though still pales in comparison to Google.

Why do some radio towers blink?
I asked my Dad, since he's a broadcast engineer, and the answer is more interesting than just "to help pilots not crash into them"!

Oops, I did it again...
I deleted all the video files from my SD card before I actually had them backed up on my NAS.
Here's how I recovered them, trying photorec, untrunc, and eventually Disk Drill: www.jeffgeerling.com/blog/2025/re...

DESCRIPTION Of course it was DNS. Is that even a question? If you ever need inspiration for finding the root cause of any problem with your application, just put on this shirt and look in the mirror...

A quick L2J video for Friday—I tested Thermal Master's P3 (provided by them), and found it a decent value if you need a smartphone IR camera. Handy for inspecting PCBs as it focuses down to 8mm, for kind of 'IR macro mode'. See more: www.youtube.com/watch?v=I3dT...

We are in the age of RISC-V chiplets, apparently.
Still testing the new DeepComputing DC-ROMA Mainboard II, with 8 SiFive P550 cores, Imagination GPU, and separate NPU chip, with 32 GB of shared RAM. The way it works is... interesting.
Stay tuned for a video. Might take a little longer than usual.

I have a feeling these will not be flying off shelves like they might've been if released in Q2 this year.
